摘要
在聚合物加工成型中,薄膜双轴拉伸成型就是平面拉伸成型,随着聚合物在固相状态下加工的日愈发展,建立这种成型加工方式下的本构模型显得很迫切,国内尚无相关报道.本文介绍了聚合物多轴拉伸网格模型的研究进展,然后建立起聚合物多轴拉伸网格模型,并在此基础上阐述了Ball模型参数的确定以及模型的实验验证,为聚合物多轴拉伸的研究提供了有益的指导.
The multiaxial stretching of polymer film was planar stretching in polymer processing,and it was very important to set up the constitutive model with the development of polymer solid processing,which was not reported yet.In this paper,the advances in study on the network model of the multiaxial stretching of polymer were introduced.The network model of multiaxial stretching was set up,and the derivation of parameter value of Ball model was pointed out.Moreover,the experimental verification was discussed,and the study topics in the (future) regarding the polymer multiaxial stretching processing were proposed.
